A Live Recording Captures Two of the Twentieth Century's Best "Mozartians."

Musicologist H.C. Robbins Landon. His new book, "Mozart: The Golden Years," traces the most troubling and creative period of the composers life, the years 1781-91. During this period, Mozart completed three controversial operas, married and wooed his wife Constanze Weber, became entangled in financial difficulties, and lived through the death of his father. In this book, the second of two volumes on the life of Wolfgang Amadeus Mozart, Landon, further explores the link between Mozart's "manic depressive disorder" and his creativity.

A decade ago, Costanzo had surgery that threatened to destroy his singing voice. Now he stars as a gender-fluid Egyptian pharaoh in the Met Opera's production. Originally broadcast Oct. 7, 2019.

Counter tenor Anthony Ross Costanzo sings in what's considered a woman's range - in the range of the castrati, men who maintained their high voices by being castrated before puberty. He's about to star in the Philip Glass opera 'Akhenaten.'
